A live-action game based on the popular anime series Detective Conan, also known as Case Closed, recently caused a bomb scare in Takamatsu, Japan.

“Escape from the Skyscraper,” tasks participants with looking for clues that lead to an imaginary bomb, which was unfortunately found by real-life detectives after the event had come to an ended.

The suspicious device was a whiteboard with red and blue wires reminiscent of the bomb in Case Closed – The Time Bombed Skyscraper, in which the heroine correctly chooses not to cut the red wire because it reminds her of the red thread of fate that connects her to the hero. The bomb disposal unit was slightly more practical. An X-ray machine revealed the object was filled with paper mache.
